を有することを特徴とする。As a means for solving the above problems, the retaining ring of the present invention uses a wire material instead of a plate material. Then, the patented hard steel wire was rolled into a rectangular cross section, bent into a ring shape, and then partially cold forged to manufacture. That is,
The retaining ring of the present invention has a main body that is obtained by rolling a patented hard steel wire into a rectangular cross section and bending it into a ring shape, and a protrusion formed by subjecting a part of the main body to cold forging. It is characterized by

め輪となる。Since the material is not punched out using a plate material but rolled into a rectangular cross section using a wire material, material loss is extremely small. Therefore, when the tool insertion hole is formed, only the hole portion becomes punching waste, the material yield is almost 100%, and the strain removal by heat treatment is not necessary, and the manufacturing cost is reduced. It becomes an inexpensive snap ring.

A C-ring for a hole, which is an example of a retaining ring of the present invention, is formed by rolling a patented hard steel wire into a rectangular cross section and bending it into a C-ring shape, and forming both ends of this main body by cold forging. And an inward projecting portion and a tool insertion hole formed in the projecting portion.

工具差し込み孔７を打ち抜く。FIG. 1 shows a manufacturing process of the hole C ring 4. In the figure, 1 is a patented hard steel wire rod, which is rolled to form a wire rod 2 having a rectangular cross section with a ratio of a width b to a thickness a of about 2, so that the width b becomes a flat surface. It was then bent into a C-shaped material 3. After that, the inwardly projecting portions 6 and the tool insertion holes 7 are formed at both ends of the main body 5 corresponding to each other by cold forging to form the hole ring product 4. As shown in FIG. 2, the protrusion 6 is formed by cold forging the tip of the main body 5 so that the inside becomes thinner,
Punch out the tool insertion hole 7.

てもよい。In the case of the shaft C ring, there is a protruding portion whose tip gradually becomes thinner toward the outside. At this time, as shown in FIG. 3, the protruding portion 6 is formed outwardly so that the tip is gradually thinned. In the case of the C ring for holes, a step portion may be provided only in the inner portion of the tip portion of the main body. As shown in FIG. 4, the protrusion 6 may be formed by cold forging only the inner portion of the tip of the main body 5 with the stepped portion 8, and as shown in FIG. It may be similarly molded at a position slightly away from.

Alternatively, as shown in FIG. 5 and FIG. FIG. 8 shows an E-ring product 9 in which protrusions 11 are formed on the inner periphery of the central portion and both ends of a C-shaped main body 10. This product 9 restrains the outer periphery of the material 3 of FIG. Is formed by cold forging the whole so that the thickness becomes gradually thinner.

低減されるため本発明の止め輪はさらに安価となる。Since the retaining ring of the present invention uses the wire rod, the yield of the material is good and the material cost is correspondingly low and the cost is low as compared with the conventional one in which the plate material is punched out. Further, since the removal of strain by heat treatment is unnecessary and the manufacturing cost is reduced, the retaining ring of the present invention becomes even cheaper.
